AUTOMATIC VALVE AND RIM.

Original No. 1,300,985, dated April 15,

reissue flled concern:

I, HARRY B. EADS, a citizen of, the United States, residin at Port Arthur, county of Jefferson, and tate 5 of Texas, have invented pertain new and useful Im rovements in Automatic Valves and Rims, ully described and represented in the following specification and the accompanyin drawings, forming a part of the same.

%his invention has reference generally to improvements in valves and more particularly relates to. an automatic valve and run.

It is the principal aim and object of this invention to provide a device of the above character designed to act in the capacity of a check when used in conjunction with suitable pumping apparatus for controlling the flow of liquids while suitable resilient means also acts in connection with the pumping means for reseating the valve.

As an additional object the invention embraces the provision of a device of the above mentioned character wherein the rim employed is of a novel form and operates with the valve body for protecting the latter during operation so as to increase the longevity thereof.

It is a more specific-object of this invention to provide a device of the above mentioned character wherein the valve casing is designed to form a seat for the rim while in addition suitable guiding means is provided with the rim and designed to co-act with the casing in guiding the movement of the valve body and rim.

As a further improvement the present invention includes the provision of improved means for governing the tension of the resilient means.

Among the other aims and objects of this invention may be recited the provision of a device of the character described with a view to compactness, and in which the number of parts are few, the construction simple and the cost of production low and the efii cienc high.

Ot er improvements and novel details in the construction and arrangement of the various parts of the apparatus will be brought out more in detail in the description to follow, which for a clear understanding of the invention should be considered in connection with the accompanying drawings forming a part hereof, and wherein is T 0 all whom it may Be it known that 1919, Serial ili'o. 221,185, filed March 8, 1918. Application for may 10, 1922. Serial No. 559,878.

disclosed for the purpose of illustration :1 convenient and satisfactory embodiment of the invention. It is to be noted in this connection that minor changes in the construction and arrangement of parts may be made without departing from the principle of operation of the various parts.

The invention is clearly illustrated in the accompanying drawings, in which Flglllfl'l 1s a vertical section of the invention.

Figure 2 is a top plan view thereof. Figure 3 is a horizontal section taken on line 3-3 of Fig. 1, and

Figure 4 is a detail of another'form of the I invention.

Similar characters of reference are employed in all of the above described views to indicate corresponding parts, except in F 1g. 4.

Referring now, more particularly, to the accompanying drawings there is provided a valve embodying a tubular attaching casing 1 formed on the end with an exterior annular flange 2 the outer surface of which together with the adjacent edge of the casing constltute a valve seat 3. Also formed integral With the casing but internally thereof and near the seat is a spider 4 which brldges the casing. A boss 5 is formed at the juncture of the arms and has the upper or outer surface thereof flush with the seat 3 and provided with an interiorly threaded socket 6 for a purpose that will presently appear. Likewise, a secondary or inner seat 7 is provided on the outer surface of the boss.

The valve body 8 is of a disk like form and preferably is constructed of rubber or a substitute therefor, being central opening 9 and having the outer edge arranged in substantial alinement with the casing when the inner surface of the body abuts the seat 3.

In order to protect the valve body from the excessive pressure of water when the valve is in use, a rim 10 is employed being .of an annular form and constructed desirprovided with a the top of the boss 5 bethe inner faceof the rim near the outer edge thereof and lie against the inner surface of to move independently of eaeh other, as

shown in Figs. 1 to 3.

As intimated improved means have been employed for yieldingly holding the valve body and rim seated. In reducing this feature of the invention to practice-a helical coil spring 12 is employed and has one end bearing against the outer face of the valve body while the opposite or outer end bears against the head 13 of a bolt 14. The inner end of the bolt is threaded as at 15 and adjustably engaged in the threaded socket 6 so that when the head is adjusted the tension of the spring will be regulated to act correspondingly on the valve body and the rim. Incidentallythe bolt 14 is arranged through the opening 9 in the body 8 so as to guide the movementof the body when the valve is in operation.

In Fig. 4 there 'is disclosed a modified form of the invention which consists in the provision of two rims 16 with guides 17, similar in construction to the rim 10 and guide 11, respectively arranged on the opposite faces of a. valve body 18 and connected thereto by rivets 15). By employing the two rims et cetera the valve body may be reversed. I

The mode of operation of the invention may be reviewed as follows:

Assuming that the parts have been assembled in the manner described and as indicated in the drawings, particularly Figs. '1 to 3, the action is the same as a check valve. When the pressure is exerted beneath the body 8 the latter will rise together with the rim 10 against the tension of the spring while water will flow through the casing 1. In reseating, the tension of the spring 12 against the valve body after the pressure diminishes reseats the valve body while the water under pressure acts as a cushion for the rim [0 which lessens the chance of breaking the rim in its seating. a

It is believed in view of the foregoing description that a further detailed description of the operation of the invention is entirely unnecessary.

As many changes could be made in the above construction and many apparently widely different embodiments of this in ven departing from the scope thereof it is intended that all mat.- ter contained in the above description or shown in the accompanying drawings shall limited sense.

be interpreted as illustrative and not in a. it is also to be understood that the language used in the following claims is intended to cover all the generic and specific features of the invention herein described and all statements of the scope of the invention which as a matter of lan-- guage might be said to fall therebetween.
